How It Works: Mode of Action
Lethal interferes with the nervous system of insects by inhibiting the enzyme Acetylcholinesterase (AChE). This causes continuous nerve firing, leading to paralysis and death.
- Contact: The pest dies immediately upon touching the sprayed liquid or treated soil.
- Stomach: Pests like caterpillars die after chewing on treated leaves.
- Vapor (Fumigant): Fumes penetrate crevices, soil, and plant canopies to kill hidden pests.
This makes it effective against both chewing pests (bollworms) and sucking pests (aphids), as well as soil-dwelling termites.

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop / Use | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 500 - 1200 ml | 200 - 300 L | 2.5 - 4 ml | 30 |

*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply during the cool hours of the day (early morning or late evening) to avoid rapid evaporation and harm to beneficial insects like bees.
- Mixing: Do NOT mix with alkaline products like Bordeaux mixture or Lime Sulphur, as this will destroy the chemical efficacy.
- Coverage: Ensure thorough coverage of foliage. For stem borers, direct the spray towards the stem/base of the plant.
- Termite Use: For building foundations, mix 1 Liter of Lethal with 19 Liters of water. Apply at 5 Liters per square meter for pre-construction treatment.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Highly toxic to fish; do not use near water bodies.
